Domain backorder is a service provided by ICANN-certified companies and it's the easiest way to obtain a good domain name that was owned by some third party and was left to expire. When the registration period of a domain is over, the latter becomes inactive, however it is not deleted immediately. Instead, its owner has 2 months to renew it. If this does not happen, the domain name enters a deletion period which continues about 5 days and after that it gets deleted, so anyone can register it. The backorder service will enable you to place an order for such a domain with a registrar company and they'll attempt to register it automatically as soon as it is on the market. Thus, you can get a short and eye-catching domain name for your website and although these domains are registered on a first -come, first-serve basis and there is no warranty that you will acquire the desired domain name, using an automated system will give you a significantly better chance than if you keep checking if the domain is deleted and try to acquire it manually.
